执行segue与标识符不会在swift 2中工作 [英] perform segue with identifier wont work in swift 2

问题描述

当用户登录应用程序时，我一直在使用此代码执行自定义segue：

I have been using this code to perform a custom segue when a user logs in to the application:

dispatch_async(dispatch_get_main_queue()){

                self.performSegueWithIdentifier("showSTPS", sender: self)

}

我目前在perpareForSegue中有这个代码（我不完全确定我是否需要它）

I currently have this code in my perpareForSegue (im not totally sure if i need it)

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?){
            if "showSTPS" == segue.identifier {
                }
}

我每次尝试执行segue时都会收到以下错误：

And I am getting the following error every time I try to perform the segue:

2015-08-31 11：56：28.998 ICEFLO [3858：651041] ***由于未捕获的异常'NSInternalInconsistencyException'终止应用程序，原因：'无法执行带标识符的segue'showSTPS' 。一个segue必须要有一个performHandler，否则它必须覆盖-perform。'

2015-08-31 11:56:28.998 ICEFLO[3858:651041] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not perform segue with identifier 'showSTPS'. A segue must either have a performHandler or it must override -perform.'

任何有关做什么的建议将不胜感激 - 请请注意，这是针对swift2 / ios9

Any suggestions on what to do would be greatly appreciated - please note that this is for swift2/ios9

推荐答案

确保在故事板中，segue类型未设置为自定义。如果您将其设置为自定义，则需要提供自己的自定义segue类。

Make sure that in your storyboard the segue type is not set to custom. If you set it to custom you'll need to provide your own custom segue class.
